Absolute Value If ABSOLUTE VALUE represents the distance a number is from zero, means all x values that are 3 units from zero. If given, what are some values that make this true? What does mean? ALL x VALUES LESS THAN 3 UNITS FROM 0.

If given, what are some values that make this true? What does mean? ALL x VALUES GREATER THAN 3 UNITS FROM 0.
